"SPRING- WHEEL.

$65,I22. Specification of Application filed May 25,

To all whom it may concern:

Be it known that I, J osnrit Ininur PALE- mssnx, a citizen of the United States, residing at Kankakee, in the county of Kankakee and State of Illinois, have invented a new and useful Improvement in Spring Wheels, port in one position of the wheel for the run of which the following is a specification.

'Ilns invention relates to a spring wheel and the object of the invention is a wheel 1 which will combine to as great an extent as possible, the resilience of a pneumatic cushion wheel and at the same time be immune from puncture, through the absence of any part which could be readily punctured or it 1 punctured wluch would be afi'ccted so far i as the use of the wheel was concerned by a puncture.

The invention consists of two concentric' rims spaced apart by means of peripherally arranged springs.

In the accompanying drawings, Figure 1. t

is a side elevation. partly in section, and parts being broken away. Fig. 2 is a sec tion upon the line 22 of Fig. 1, both side plates and dust guard being shown. Fig. 3 is a detail sectional view illustrating a chain construction.

In these drawings 1 represents a wheel ot i the ordinary constrtmtion, said wheel being provided with a wooden telly! which 'carries a metal tire 3. This wheel is complete in itself and may be the ordinary wagon or limggy wheel. Concentric with this wheel is an iron rim 4 which carries a rubber tire 5 of: any desired kind. The rim 4 is of considerably gr ater diameter than the tire 2i, and carries upon its opposite sides iron plates 6 which iron plates not only overlap the rim of the wheel 1 thus covering the space between the wheel 1 and the rim 4 but they also project beyond said rim 4 thus serving as flanges for holdin the rubber tire 5 in place. Suitable bolts I pass through the plates 6 and through the space between the rim 4 and the wheel 1, said bolts being ad-' jacent the rim 4 and-between the plates 6. These bolts carry short sections of pipe 8 which pipe sections form sleeves for the bolts.

.' Compound springs t) bear upon the inner l face of the rim t and upon the periphery of the tire 3, each end of said springs being bent around and secured to one of the pipe sections 8. These springs serve to space the. rim 4 from the wheel I and act as a sup- :t and in another position For the wheel I. In order to prevent the rim 4 being i twisted out oi. place l connect the rim -l amt the wheel 1 by means of chains to arranged at a tangent to the wheel 1 so that they do not interfere with the spring action ot the wheel, and to prevent any rattling ot the chains they are preferably inelosed in rubber sleeves II. I also cover the joint between the iron plates (3 and the wooden t'elly 2 with strips of leather or rubber as shown i at 12, such strips )reventing dust. and dirt 5 from working in between the plates (3 and the sides of the telly, but being tlexible ati lowing tree sliding movement of the said plates upon the telly. strip 1 of metal holds the rubber or other covering tirmly in place.

What I claim is:--

The combination with n ventcie wheel, of a concentric rim oli greater diameter than the wheel spaced theret'rom. metal plates carried by said rim and overlapping tlle. wheel upon opposite sides, bolts carried by Said metal plates, said bolts passing through the space between the rim and wheel. munpound curved springs having their central ltlSl'll'll llllhltll PAU LISSEN.
